Hi Max,
I have an ad on Gumtree for a Chonda I put together, good Sanli motor, good little 16 inch mower for somebody with a small area to mow. I have it on there for $70 and I had a bloke ring a few days ago and he said he would give me $50 for it. I said no and hung up on him. He spent the next half hour abusing me and carrying on like an absolute turkey till I blocked him. There is plenty like that out there and makes you wonder if it is all worth the effort.
